IMPROVEMENT m CAR-BRAKES.

Specification forming part of Letters Patent No. 153,857, dated August4, 1874; application filed July 1, 1874. v

To all whom z't may concern:

Be it known that I, WILLIAM H. H. SNELL- BAKER, of St. Louis, State ofMissouri, have invented an Improved Gar-Brake, of which the following isa specification:

The object of my invention is to construct a simple and efi'ectivebrake, which can be applied to either horse or steam cars; and itconsists of a semicirculariron casting, upon andbetween which arectangular segment slides, and whose circumference is grooved toreceive a-brakechain. One half of the inner face of the casting isserrated to receive a pawl situated on a foot-1ever, which is connectedwith the segment-arm, which is attached to a cast iron stool by a loosewrist.

By reference to the accompanying drawing its construction will bereadily understood.

A is a semicircular frame or casting, which has teeth a on half of itsinner surface, which is bolted to the car-platform parallel to the endof the car by its flanges b. The segment B, whose outer surface isgrooved to receive a brake-chain, i, and is connected with thebrake-lever O by means of its arm D at the loose wrist d of thecast-iron stool E, is made.

to slide upon and between the frame by pressing the foot-treadle e,which throws the pawl f in or out of gear with the teeth a by means of aspring, g, operated by a rod connected with the foottreadle e. The brakechain passes from the segment B through the plat form of the car betweentwo pulleys, h, and connect with the brake-rods beneath the floor of thecar.

' The operation of my improved car-brake will be perceived when it isstated that by pressin g the foot-treadle e the pawl f attached to therod 0 and impinging upon and against the face of the treadle e isdisengaged from or united to the teeth a by means of the spring 9.

The brake is adapted to steam'cars by dispensing with the treadle e andlengthening the lever 0.

By constructing my brake in this simple manner I secure the advantagesof greater power and instant application, as well as greater safety, byenabling the driver to de-' vote himself to managing his horses.

Upon street-railway lines where drivers act as conductors it will enablethem to make change or sell tickets without inconvenience.

What I claim, and desire to secure by Lettei's Patent, isr Thecombination of the treadle c with the rod. 6, pawl f, spring 9, and arm0 of the segmentB, in the manner and for the purpose set forth.
